Human health risk assessment related to blue-green algae mass development in the Kuibyshev Reservoir

Abstract

Health risk assessment related to water quality and microcystin contamination of water in the Kuibyshev Reservoir was conducted in August 2012 during the period of algal bloom. The health risk during recreational activity was estimated for potential exposure to extracellular microcystins. Microcystin content in water measured by the indirect competitive ELISA method was in the range from 0.21 to 26.96 μg L−1. The results of the present study show that the health risk can reach a dangerous level even at 1 h of exposure due to the high concentration of extracellular microcystins in the water.

Estimation of atmospheric methane levels over the Republic of Tatarstan (Russia) territory in 2019–2023 using satellite remote sensing data: effects of anthropogenic and climate drivers

“…The total area of the republic is 67.8 thousand square kilometres, with a population of 4 million people. The capital of the Republic of Tatarstan, Kazan, is located 800 kilometres east of Moscow [9].…”

Responses of the Proteome and Metabolome in Livers of Zebrafish Exposed Chronically to Environmentally Relevant Concentrations of Microcystin-LR

“…Although variations have been reported among all of the amino acids, substitutions of the variable l -amino acids X and Z in positions two and four are most prevalent , MC-LR is one of the most common and potent variants, which is why it has been the most widely studied. In most cases, concentrations of dissolved MCs in water are relatively small, within a range of 0.1–10 μg/L, whereas cell-bound concentrations are several orders of magnitude greater. − MCs are of concern due to their adverse effects, such as hepatotoxicity, carcinogenicity, reproductive toxicity, neurotoxicity, immunotoxicity, and endocrine-disrupting effects. , Exposure of humans to MCs can occur via ingestion of contaminated drinking water and/or consumption of cultivated plants, aquatic products including fish and blue-green algae supplements (BGAS). , In 1998, the World Health Organization (WHO) established a provisional guideline value of 1 μg MC-LR/L in drinking water. , In 2010, the International Agency for Research on Cancer (IARC) classified MC-LR as being “possibly carcinogenic to humans” (Group 2B carcinogen)…”
